printer discovery (STR #3065)

in length (STR #3072)
- Fixed pdftops issues with page sizes (STR #3063)
- Fixed pdftops issues with Ghostscript (STR #3062)
- The scheduler incorrectly registered default profiles for PostScript
printers with no specified colorspace.

- The commandtops filter incorrectly used the JCLBegin code to end
its jobs.
- The default BrowseLocalProtocols value was not set properly.
- Since the commandtops filter does not actually support ReportLevels
